My router (Archer VR200 V2) and line has been stable but last night, our devices couldn't connect to the internet but the router showed the internet status as connected so we just left it and went to bed. I went to check it this morning but same result so I restarted the router via the router's settings page and the internet is now working fine but speeds has lowered.
Before the router was restarted, the downstream max rate was around 68000 and downstream current rate was 72000 with 3dB SNR margin, so do I need to wait for DLM to bring down the SNR margin as I believe this is the case affecting the speed?
It could be just a matter of days, just keep a stable connection. No restarts.
